Question

If you have a liquid flow of 500 gallons per hour thru a 4" line that passes thru a 2" valve What is the flow

Answer 1

If you have a flow rate of 500 gal/hr then that is the flow rate.

The velocity through the 2" valve will simply be greater than in the 4" line.

You have the same thing at the Metering point where the velocity through the o*****e Plate or Venturi Tube increases. This produces a Pressure Differential across the metering device that is translated by the instrumentation into Flow Rate.

dettom, mensajer, what qualifies you to give 'thumbs down' here ??

Answer 2

500 gallons per hour,  the flow will remain the same, the speed is what is going to change due to the change of area of the pipes of whatever it's passing through.

hope this helps.

Answer 3

If 500gallons per hour passes thru a 2inch valve

Flow = 500 gallons/hour or

          500X60= 30,000 gallons per minute

Answer 4

it would depend on if this was supply or discharge on the supply your max is 700   gph that is at a pressure of 80lbs psf
